A water jet pump (see Fig. P5.17) involves a jet cross-sectional area of \(0.01 \mathrm{~m}^{2}\), and a jet velocity of \(30 \mathrm{~m} / \mathrm{s}\). The jet is surrounded by entrained water. The total cross-sectional area associated with the jet and entrained streams is \(0.075 \mathrm{~m}^{2}\). These two fluid streams leave the pump thoroughly mixed with an average velocity of \(6 \mathrm{~m} / \mathrm{s}\) through a cross-sectional area of \(0.075 \mathrm{~m}^{2}\). Determine the pumping rate (i.e., the entrained fluid flowrate) involved in liters/s.
